Power supply for security systems

The ALTRONIX AL400ULPD4 converts a 115VAC 60Hz input into 4A continuous current at 12VDC or 3A at 24VDC. It is designed for installers who need a single chassis to feed multiple access-control or surveillance devices from one mains connection.

Sustained load behaviour

Four fuse-protected Class 2 power-limited outputs distribute the rated current without exceeding the listed limits. The supply maintains its 12V or 24V rails under continuous demand rather than only in short bursts, so attached locks, readers or cameras receive stable voltage during extended operation.

Build and mounting implications

A wall-mount enclosure lets the unit sit close to the protected circuit runs, reducing cable length and voltage drop. Fuse protection on each output isolates a fault on one branch without cutting power to the others, simplifying troubleshooting on site.

Questions about this item

How much heat or noise does the AL400ULPD4 produce when running all day?

The unit uses a linear design with no fan, so it runs silently and generates only modest warmth at 12 V 4 A or 24 V 3 A continuous load.

What must I already have on site for the AL400ULPD4 to work?

You need a 115 VAC 60 Hz mains circuit and four sets of low-voltage wiring to connect cameras, locks or controllers to the fuse-protected outputs.

Will the AL400ULPD4 power my older 12 V analogue cameras alongside new 24 V IP devices?

Yes — the supply delivers 12 VDC at 4 A or 24 VDC at 3 A across four Class 2 fuse-protected outputs, so both voltage devices can share the same unit.
